curious about why you can have an avi with drugs on it. im down, but still, this board seems to be very strict.Formosa is male. Regalis is female.

Dorsal sexing is not 100% accurate unless it is mature. Ventral sexing is 99% accurate with a clear photo.
back on topic, the regalis looks male to me as well.
